Procurement Notes
Verify the specific suffix 'H' on the packing code, as it indicates AEC-Q101 qualification and compliance with JESD 201 class 2 whisker testing standards. Confirm RoHS compliance status and halogen-free material declarations against the manufacturer's latest documentation before finalizing procurement specifications.
Selection Notes
Select this component when an 82 V Zener diode with automotive-grade reliability is required. Ensure the circuit design accommodates the specified 1 W power dissipation limit and the 175 Ohm dynamic impedance characteristics. Verify that the DO-41 through-hole package aligns with the target PCB layout constraints.
Part Context
This part belongs to the 1N4761AH series of glass passivated silicon Zener diodes produced by Taiwan Semiconductor. The series covers various voltage ratings within the DO-41 package format. The 'R1G' designation typically refers to the reel packaging configuration and lead finish specifications provided by the manufacturer.
Replacement Considerations
Cross-reference with other manufacturers offering the standard 1N4762A JEDEC specification. Verify that any substitute maintains the 82 V nominal voltage, 1 W power rating, and DO-41 package dimensions to ensure mechanical and electrical compatibility.
